</blockquote><h4><a name = "tag_000_000_231">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>calendar</i>
utility
consults the file
<b>calendar</b>
in the current directory
and writes lines that contain today's or
tomorrow's date anywhere in the line to standard output.
On Fridays and weekends,
<i>tomorrow</i>
extends to the following Monday, inclusive.
</blockquote><h4><a name = "tag_000_000_232">&nbsp;</a>OPTIONS</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_000_233">&nbsp;</a>OPERANDS</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_000_234">&nbsp;</a>STDIN</h4><blockquote>
Not used.
</blockquote><h4><a name = "tag_000_000_235">&nbsp;</a>INPUT FILES</h4><blockquote>
The
<b>calendar</b>
file in the current directory is a text file.
Each line can contain text that includes a string, in any
location, that is interpreted as
<i>today</i>'s
or
<i>tomorrow</i>'s
date.
Month-day date formats such as
<i>Aug.</i>
<i>24</i>,
<i>august</i>
<i>24</i>
and
<i>8/24</i>
are recognised.
</blockquote><h4><a name = "tag_000_000_236">&nbsp;</a>ENVIRONMENT VARIABLES</h4><blockquote>
The following environment variables may affect the execution of
<i>calendar</i>:
<dl compact>

<dt><i>LANG</i><dd>Provide a default value for the internationalisation variables
that are unset or null.
If
<i>LANG</i>
is unset or null, the corresponding value from the
implementation-dependent default locale will be used.
If any of the internationalisation variables contains an invalid setting, the
utility will behave as if none of the variables had been defined.

<dt><i>LC_ALL</i><dd>
If set to a non-empty string value,
override the values of all the other internationalisation variables.

<dt><i>LC_CTYPE</i><dd>
Determine the
locale for the interpretation of sequences of bytes of text data as
characters (for example, single- as opposed to multi-byte characters
in input files).

<dt><i>LC_MESSAGES</i><dd>
Determine the locale that should be used to affect
the format and contents of diagnostic
messages written to standard error.

<dt><i>LC_TIME</i><dd>
Determine the format of the date
strings recognised by the
<i>calendar</i>
utility.

<dt><i>NLSPATH</i><dd>
Determine the location of message catalogues
for the processing of
<i>LC_MESSAGES .
</i>
<dt><i>TZ</i><dd>Determine the timezone used to qualify
the date strings recognised by the
<i>calendar</i>
utility.
